Module mysql.unsafe.commands
Use a DB via plain SQL statements (unsafe version).
Commands that are expected to return a result set - queries - have distinctive
methods that are enforced. That is it will be an error to call such a method
with an SQL command that does not produce a result set. So for commands like
SELECT, use the query functions. For other commands, like
INSERT/UPDATE/CREATE/etc, use exec.
This is the @system version of mysql's command module, and as such uses the @system
rows and result ranges, and the Variant type. For the MySQLVal safe
version, please import mysql.
